J. REPETTO. BOTTLE STOPPBR.- APPLICATION FILED MAY 11,1907.

ATTORNEY I WITNESSES mvrrn s'ra BOTTLE-STOPPER.

T 0 all whom itrmay concern: I

Be it known that I, J OHN REPETTO, a citil zen of the United States, and a resident of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a full, clear, and complete disclo- I sure. I

The chief object of my invention is to pro- I vide a cheap, durable, and efficient hollow stopper formed of sheet material.

With this and other objects in view, the 1 invention consists in the device hereinafter described, claimed and illustrated in the accompanying drawings, in which Figure 1 is a longitudinal section of one embodiment of my invention, as applied to a bottle; Figs. 2, 3, and 4 longitudinal sectio -s of modified forms of this invention; Figs. 5, 6, 7, and S longitudinal sections of modified forms of stoppers; Fig. 9 a side elevation showing the exterior of one of the forms of stoppers illustrated in Figs. 1, 2, 3, 7, and 8; Fig. 10, a side elevation of the stopper shown in Fig. 4; Fig. 11 a side elevation of a stopper showing a form of opening for the reception of the wire fastener; and Figs. 12, 13, and 14 are a section, an elevation, and a top plan view respectively of a further modifica tion of this invention.

Referring to the drawings, the exterior shell of each stopper, shown in the various forms, comprises two part-s 1 and 2, having overlapping edges 4 and 5, binding the same together. In Figs. 1, 6, and 12 these edges are shown as slightly corrugated so as to interlock. In Figs. 1, 2, 3, 7, and 8 these overlapping edges form a longitudinal central seam or division of the stopper, as shown exteriorly in Fig. 9 by line 99, while in Figs. 4 and 6, the seam or division extends in a plane transverse to the axis of the stopper, as is shown by line 1010 in Fig. 10.

In Figs. 1, 2, and S the overlapping edge of one part of the'stopper is flanged inwardly to form a channel or rabbet for the reception of the edge of the other part of the stopper, the two parts being so proportioned as to con- S'pecification of Letters Patent.

stitute a tight and rigid fit together, the flanged portions tending to stiffen the struc 1 ture in 4 and 5 the parts are bound in a similar manner, but the division as heretofore stated is in a transverse plane; in Fig. 6, the lower part of the stopper has its edge outw ardly flared, and the upper part of the stop per has its edge rolled or turned over the l Patented Dec. 10, 1907 Application filed May 11.1907.- Serial No. 373.032.

flared edge of the lower part after the two parts are put together; and in Figs. 7 and 8, the parts are so formed that one edge makes a tight fit within the opposite edge.

Each form of stopper shown is provided with diametrically opposite apertures 6 formed in the upper portions of the sides of the stopper to receive the wire loop 7, which is a part of a w ell-known wire combination for fastening the stoppers in the bottles 8.

These apertures are formed by stamping the sheet material so as to leave inwardly extending flanges 11 and 12 integral with the sides, and in Fig. 1 these flanges are shown drawn out and overlapping at their edges to constitute a brace to keep the stopper from collapsing, and also to hold the stopper more firmly together; in Fig. 2, these flanges are extended inwardly but comparatively short distances and fit tightly within a separate tube 9, which performs the same functions as the overlapping flanges in Fig. 1.

In Figs 3, 4, 6, and 7 the tube 9 is shown fitting within the flanges about the aperture, but extending at each end to the outer surface of the stopper.

I form the stopper preferably of sheet steel, but I do not wish to limit myself to this. material, as copper, celluloid, or any other suitable sheet material, may be used. After the parts ofthe stopper are fully assembled, the whole may be plated with sil-' ver, nickel, or other suitable metal, or may be otherwise coated with porcelain or other material to form a practically undivided surface 14, as shown in the sectional views, and prevent any possible leakage through the stopper. This protective coating in addition to performing the above function also serves to more rigidly bind together the assembled parts and so produce a much more durable stopper. Between the stopper and the mouth of the bottle, the usual rubber washer 15 is applied. When a stopper is divided longitudinally or transversely, as shown in the drawings, the wire fastener holding the stopper in the bottle, tends also.

to hold the two parts of the stopper together.

In Fig. 11 I have shown the preferred form of opening to be used in this construction, which is substantially triangular in shape, with convex lower sides meeting in a concave lower edge, shaped to conform tothe sides and curvature of the wire which it contains, and. to hold the wire from slipping laterally. In this figure I have also shown a stepped formation of the conical exterior of the stopper.

Figs. 12, 13 and 14 show a modification of the invention in which the stopper is divided transversely, the edge of the upper part being flanged outwardly and-the ed e of the lower part being flanged over the edge of the upper part. In these views is also shown the manner of applying the name of the manufacturer or other printed matter to the top and side of the stopper. Each of the forms shown is thus lettered by stamping or engraving or by any other suitable process. I prefer to stamp or emboss the said printed matter upon the parts of the stopper before the same are assembled, as such embossing adds greatly to the stiffening and strength of the stopper. Fig. 13 shows a modified form of opening 6 which is bounded by converging lower sides forming a narrow groove to prevent the wire from slipping.

l/Vith this construction in mind, it is evident that this stopper is superior to the ordinary forms of cork or solid porcelain stoppers in its durability, as both cork and porcelain are easily broken in ordinary usage. Furthermore this improved stopper is much lighter in weight than the solid stoppers of porcelain or similar material, and can be constructed at much less expense.

I have shown. herein only a few of the various forms in which this stopper may be used, and I do not want to be limited to any particular form, as the invention could be applied to any form ofstopper now in use.

Having thus fully described my invention, what I claim and desire to secure by Letters Patent of the United States is z- 1. The combination with a bottle, of a hollow stopper of substantially conical shape 'comprising a plurality of parts of sheet material and means to fasten said stopper into the,

bottle, said bottle and fastening means coacting upon the conical surface of the sto er to wedge the parts thereof together.

2. A hollow stopper formed of sheet material. and comprising two parts joined longitudinally of said stopper.

3. A hollow stopper formed of sheet material and comprising two parts having overlapping edges forming a joint extending longitudinally of said stopper.

'4. A hollow stopper formed of sheet material and comprising two parts having overlapping edges, one of said edges being flanged inwardly to receive the other of said edges.

5. A hollow stopper formed of sheet material comprising two parts having overlapping edges forming a joint extending longitudinally of said stopper, said stopper being provided with a transverse aperture for the reception of a fastening device.

6. A hollow stopper formed of sheet material, and comprising two parts fastened together, and having a transverse aperture, the

sides' of said stopper being turned inwardly about said aperture to form inwardly extending tubes.

7. A hollow stopper formed of sheet material and comprising two parts fastened together, and having a transverse aperture, the sides of said stopperbeing turned inwardly about said aperture'in the form of flanges, and a tube connecting said flanges.

8. A hollow sheet metal stopper provided with an internal tube forming a transverse aperture for the reception of a wire fastening, said aperture being substantially triangular in transverse section and bounded by convex lower sides and a concave lower edge proportioned to receive said wire fastening and to hold the same from slipping laterally.

9. A hollow stopper formed of sheet material and provided with an internal tube forming a transverse aperture for the reception of a wire fastener, said aperture. being bounded by converging lower sides forming a narrow groove to prevent the wire from slipping.

10. A hollow stopper built up of parts formed of sheet material having interlocking edges extending longitudinally of the stopper.

11.. A hollow stopper built up of parts formed of sheet material and having corrugated interlocking edges.

12. A bottle stopper built up of a plurality of parts of sheet material, one of said. parts being provided with an embossed portion to identify the stopper and stiffen the same.

13. A hollow stopper composed of a plurality of parts having overlapping edges, and retained together by the frictional contact of said edges, a coating over the assembled parts to further secure the parts together and prevent the accumulation of foreign matter within said stopper.

1 1. The combination with a bottle, of a hollow stopper comprising a plurality of parts of sheet material, and means to fasten said stopper into the bottle, said bottle and fastening means coacting upon the surface of the stopper to force the parts thereof together.

15. A hollow stopper composed of a plurality of parts having overlapping edges, and retained together at their edges, and a coating over the assembled parts to further secure said parts together and to prevent the accumulation of foreign matter within said stopper.

I11 witness whereof I have hereunto set my hand this 10th day of May, A. D.', 1907.
